Hey sorry for the late reply! Holidays here in the USA.
So your “VRAM” is your Video RAM (Random Access Memory) that is dedicated to video rendering, usually only on a dedicated video card.
So we have established that the brand of the card is an AMD Radeon - but there are many many of these and that unfortunately doesn’t tell me what your VRAM actually is. 
Try typing “dxdiag” into your start menu and running that, it should bring up this window, then tab over to your first display and it SHOULD say there.
